  1. Key Stage 3 A suggested Year 9-10 Project: To Manufacture a Pocket Torch Manufacturing RA Moffatt WELB

  2. Key Stage 3 A Pocket-Pen Torch Design RA Moffatt WELB

  3. Shown is a design for a pocket – pen torch. It was envisaged by the designer that this product would become useful in certain situations. Design Tasks: You are about to make such a torch just like this! However you will have the opportunity to personalise your pen-torch, by designing the following parts: - The clip is to be of your own design. The end of the torch is to be made from brass or aluminium and turned on the centre lathe. a) What materials could the clip be made from? b) Why do you think these materials are suitable? c) Show by means of a sketch how the clip may be fitted to the body of the pen torch?

  4. A Pocket-Pen Torch Design • Investigation: • You now need reference material to help with ideas? • Before manufacturing start by making a study of the following: - • Different designs of torches to see how the different parts fit together • The shape and style of pen clips Homework 1: Make a collection of five different clip designs from old catalogues, brochures, magazines, Internet, etc Can you thing of any other item or product that may be carried in ones pocket that would require some type of clip? From the materials you have collected design a suitable clip that could be attached to the cylindrical torch. Use notes along with your sketches to help explain your ideas.

  5. A Pocket-Pen Torch Design Task 1: Write a problem identification for this product. In other words list or describe three situations that this product would be helpful in? Design Brief: (Remember a design brief is a short statement describing the task) Your teacher will help you write the design brief • Design Tasks: • Design a clip suitable for the pen-torch that can easily be attached to the main • body of the pen. • Select your best design and make a paper or card template (full size) • Show clearly using sketches and notes two different methods of securing • the clip to the pen body • Design a simple cylindrical end plug that will protect the bulb should the • torch drop. • Show how this plug is to be fitted to the main body of the torch?

  6. Shown below are some of the main components used to make the torch work. This is a simple electric circuit or electrical system and it is important that you Understand how this circuit works? 2 AAA Batteries Push-to-Make switch • Draw the simple electrical circuit using the Crocodile Technology software • and test this circuit. • Re-Draw this circuit using the correct symbols and explain how this circuit • works?
